This kind of works, with some limitations (I'll ask to remove one 
limitation):


import std.stdio, std.conv, std.typecons;

class Foo {
     int x;
     this(int x_) { this.x = x_; }
     override string toString() { return text(x); }
}

void main() {
     // scoped!Foo[10] foos;
     typeof(scoped!Foo(1))[10] foos; // Not initialized.

     foreach (i, ref f; foos)
         // f = new Foo(i * 10);
         // f = scoped!Foo(i * 10);
         f.x = i * 10;

     // writeln(foos);
     foreach (ref f; foos)
         writeln(f.x);
}
